Problems solved by technology

However, this signal light control scheme needs to train and learn a large amount of data before obtaining an ideal signal light timing, which makes the performance of the signal light control system poor during the initial interactive training process, and the feasibility in practical applications is poor.

Abstract

The present invention provides a control method, device and computer-readable storage medium for a traffic signal light. The method includes: acquiring training samples according to historical control data, wherein each training sample includes historical signal light timing, historical traffic measurements and historical traffic indicators; performing training according to the training samples to obtain a mapping function; acquiring actual traffic measurements and actual traffic metrics Traffic index; according to the mapping function, the actual traffic measurement and the actual traffic index, the timing of the signal light to be output is calculated. According to the present invention, the problems of poor performance of the signal light control system and poor final performance of the signal light control system due to errors in the traffic model during the initial interactive training process of the existing signal light timing scheme can be effectively avoided. The initial performance and final performance of the signal light control system are improved.

Description

technical field [0001] The present invention relates to the technical field of traffic control, and more particularly, to a control method, device and computer-readable storage medium for a traffic signal light. Background technique [0002] With the acceleration of urbanization and the popularization of motor vehicles, people are faced with the problem of increasing traffic congestion. In the case of not adding new traffic roads, it is an effective way to solve the problem of traffic congestion through reasonable traffic control to improve the utilization efficiency of roads, thereby improving traffic efficiency. [0003] At present, the traffic model-based signal light control scheme has been applied in the signal light control system. The traffic model usually includes a traffic flow model, a queue length model, a delay model, etc., which establishes the mathematical relationship between traffic measurement, signal light timing, and traffic status or traffic indicators. ...
